And even there, the problem isn't always the soundcard drivers --
softsynths often have incredible latency issues when trying to play them
live, since the soundcard or USB keyboard driver gets the keypress, has
to pass that information on to the softsynth which has to get that
sound's data from memory and pass that onto the CPU to be processed,
then that gets passed to the soundcard to be sent to the speakers.
For extremely low-latency while using soft-synths (such as Finale
Soundfont or GPO playback) an extremely fast CPU with tons of RAM is
required.
Running a midi keyboard directly into the soundcard to play the
soundcard's built-in synth (even if the sample are held in RAM such as
with Creative Audigy soundfonts) is very direct and unnoticeable
latency. Once a USB keyboard is added into the mix a bit more latency
creeps in, and once a USB keyboard along with softsynth playback such as
through Finale/GPO, a lot more latency is introduced.

that has to manage the signal in real time and convert it in a sound. If
the card has poor drivers, the latency occurs.
You should specify if you need a soundcard which has an inbuilt
soundbank (like the Creative Audigy series) or you need simply a
reliable audiocard to manage sounds through Finale soundfonts.
In the second case I'm really satisfied with this USB Audio Card

I have been very dissatisfied with a keyboard (Behringer UMX61) that I
bought recently because of the irritating latencies between key press and
sound. I thought I might get used to it, but have not been able to. It
plugs
into a USB port (Windows XP) and perhaps that accounts for the problem.
What combinations of MIDI keyboards and sound cards have you used that
you
recommend?
